Answer:
75.36
Step-by-step explanation:
3.14(pi) x 24(diameter) = 75.36(circumference)
Answer:
14%
Step-by-step explanation:
First find the total for all the dresses.
Total = 14 + 37 + 22 + 56 + 33
Total = 162
Now you are concerned about the blue dresses.
% = (22 / 162) * 100 = 13.58 %
Rounded to the nearest % it would be 14%
The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.
Answer:
Step-by-step explanation:
Given that
Sample size = n = 8: sample mean = 36.5 and s = sample std dev = 7.4 minutes
98% CI using t = (28.7, 44.3) with margin of error as 7.8
Now if sigma = population std dev is known we use Z critical value
Margin of error = 2.33*8.7/\sqrt 8 = 7.167
CI = (36.5 ±7.167)
This is not wider than that used using t distribution
The margin of error of u is ___7.167
98% confidence interval using the standard normal distribution is (29.333__,43.667__)
d)the confidence interval found using the standard normal distrubution is narrower than the confidence interval found using the students t-distribution
I have no idea what to do in problem 1
but I will do problem 2
A. 2⁵ = 32 (2×2×2×2×2=32)
B. 4³/2 = 32 (4×4×4=64 and then 64÷2=32
the others are not equal to 32
